O2 has announced it has secured a new five-year deal to provide free Wi-Fi for 1,200 McDonald's restaurants across the UK.

The service agreement will require potential users to sign-up with O2's network. They can then use the service at any McDonald's or at any of O2's Wi-Fi hotspots.

"A year ago we set out our ambition to transform public Wi-Fi in the UK by offering a fast and reliable public Wi-Fi connection that is genuinely free for all, no matter which mobile or broadband provider they are with. This announcement builds on the significant partnerships already secured by O2 Wifi in the past 12 months, enabling millions of people the length and breadth of the UK to access the internet for free whilst on the move," said Gavin Franks, the Managing Director of O2 Wifi.

According to Mark Fabes, the IT Director for McDonald's UK, the service was launched in 2007 and the fast food chain has since become the UK's biggest provider of free wireless internet access.

"Since then usage has soared, with growing numbers of professionals making use of our restaurant wifi for business meetings and remote working, as well as families and individuals being able to use the network to check emails, shop online or keep up to date with the latest news," Fabes explained.

According to the company's recent figures, 750,000 McDonald's customers log in every month.

"For the three million people we serve in our restaurants each day we believe that O2's mobile expertise and enhanced quality of network connectivity will deliver a fast, safe and secure service for our customers to use when they visit us," added Fabes.
